Where are Sea Lampreys Controlled

The Great Lakes Fishery Commission works with Fisheries and Oceans Canada, the U.S. Fish and Wildlife Service, and the U.S. Army Corps of Engineers to undertake sea lamprey control. The control program uses several techniques to attack sea lampreys. This effort (known as "integrated sea lamprey management") includes:
  • sea lamprey assessment
  • lampricide control
  • sea lamprey barriers
  • sea lamprey traps
